4 Claims. (01.132 34) This invention relatesgenerally to hair curlers and more particularly to curlers of the type adaptedto be used for associating a hair curl ment over the device shown my co-pending application Serial No. 360,035, filed October 7,

1940. In myaforesaid co-pending application I have disclosed means for impositively gripping oraccommodating one leg of a conventional spread hair clip. That constructionnecessitates the .use of an internally positioned elongated member, the relatively long external surface of which cooperates with the elongated internal surface of a companion member to provide an axially extending recess receiving one leg of the hair clip.

The present invention contemplates an extremely simplified and more .efficien'tl operable device which precludes the necessity of forcingthe clip along the elongated surfaces just referred to.

More specifically, the invention contemplates a hair curler device which is generally tubularin 1 construction capable of being 'formedfrom sheet metal or plastic materials, said tubular structure being provided at one extremity with an improved efliciently operable arrangement for spreading a hair clip or bobbiepin and impositively securing one leg of the spread hair clip or bobble pin in place. l t

Still more specifically, thepresent invention contemplates a hair curlingdevice of the type referred to above wherein oneleg of a bobbiepin may be initially inserted at an angle to the axis of the tubular structure and easily moved thereinto so as to facilitate the initial spreading of the pin and thereby enhance the ease with which a hailrl curl may be moved into association there wit i i i The foregoing and other objects. and advantages will be more apparent from the following detailed description when considered in connection with the accompanying drawing, wherein:

it will be seen thatone embodiment of the invention contemplates :a haincurlin'g device which includes an external tubular structure or elonsmooth outer peripheral surface for receiving or accommodating the h'airstrandsto be curled.

The member i4 is arcu'ate in cross section so as to conformsubstantially to the peripheral contour 'The sleeve or tube I0 is telescopically slidable on the support member l2 from the inner or retractedposition, shown in Figures 1 and 3 to the outer or extended'position hown in Figure 4. The parts are guided in their relative telescopic movementby an inward protuberance 22 extending into a longitudinal slot 24in thetube or rod It.

This. protuberance also, by engaging the ends of the slot. limits the relativetelescopic movement of these parts. l

A leaf spring 25 of U-shaped configuration is interposed between the innersurface of the manually operable finger l 6 and the surface of the tube l2, as clearly illustrated in Figure 5. The center portion of the spring rests upon the pivot pin 20.

A suitable knobor handl 28 is'secured to the extremity ofthe' tube or rod 12 many. suitable manner. i i

In the outer endof the sleeve i0 is rotatably mounted a hair clip holder comprising a thimblelike shell or cap 38 havingarelatively thin cam shaped outer end wall 32 provided with anaxial opening 34 to receive one leg 36 of a conventional hair clip orbobbie pin designated generally by FFICE i the numeral 38. The other and corrugated leg 46 of the clip is designed to engage the peripheral outer surface of the holder at the rounded corner or margin of the holder. To secure the holder or cap against axial displacement with respect to the sleeve I6 while permitting its free rotation relative thereto; the holder is formed with an holder engages only a relatively small area or annular groove 42 which receives the complementary annular bead 44 formed in the sleeve l6 adjacent its outer end. To facilitate spreading'of the clip or bobbiepin at a wide angle to the hair receiving surface of the tube IIJ without interfering with the substantially free and ready insertion of the clip into the holder, I mountwithin the holder 36 a cylinder 46 having a spoked'disklike member 48. at its inner end. The disk-like member 48 is formed by angular spaced relatively.

narrow radial spokes 56 extending from the outer radial edge of this member to a central relatively pointed dome-shaped cam member 52 concentric 'to the axis of the holder and the opening 34. The

spokes 50 are preferably also made dome shaped in cross section, as best illustrated in Figure 8, so as to have a camming action when engaged by the end of the leg 36 of the hair clip or bobble pin. The cylinder 46 may be secured in any convenient manner to the inner surface of the holder 30 and is preferably positioned relatively adjacent the rounded or cam end 32 of the holder.

It will be noted that on insertion of the leg 36 of the hair clip or bobbie pin 38 in the opening 34 at an angle to the axis of the curler, preferably by tilting the clip slightly downward at its outer end while inserting the leg 36, the end of the leg 36 will first engage the dome shaped cam 52 slightly above the'relativelypointed end thereof and as the clip is further inserted, this cam directs the leg 36 through th opening between adjacent spokes and into engagement with the inner surface of the holder at'an angle thereto. This inner surface of the holder then bends the end of the leg 36 downwardly about the point of engagement between the leg and the dome shaped cam 52 or an edge of one of the spokes B. This bending of the free end of the leg 36 of the clip'facilitates the spreading .of the leg 40 of the clip, as on insertion of the clip,'the leg 46 engages the cam end 32 of the holder. Thus this cam end 32 may be made relatively abrupt in character, that is rounded but not pointed, so that when the clip is fully inserted, the leg 40 will extend at a wide angle relative to the hair receiving surface of the sleeve ID so that the curled hair may be pulled off endwise of the sleeve under the end of the leg 40 of the clip, as indicated in Figure 4. a In my prior application, previously mentioned, the spreading of the leg 40 of the clip was facilitated by means of an elongated, bullet-shaped member in the clip, holder, such member forming with the innersurfaceof the holder a longitudinally extending recess parallel to the axis of the holder which was: substantially the same width as the leg of the hair clip so that as the clip was inserted the confining ofthe inserted leg in such an axially parallel recess aided the spreading of the clip. In the present construction this is accdmplished by means of the disk-like member 48 without confining the end of the clip between gripping surfaces which resist the insertion of the clip and require relatively strong pressure on the clip to effect the full insertion of the clip in the holder. In this present construction, the advantageous effect of the spreading of the clip by means acting on the inserted leg of the clip as well as the other leg of the clip is retained, but

the resistance to the insertion of the clip is materially reduced, for the inner surface of the length of the leg 36 and the leg of the clip engages the deflector or dome-shaped member 52 substantially at a point. Thus axial resistance to the insertion of the clip is substantially eliminated and a minimum of force is thereby required to beapplied by the user to insert and cause the wide angle spreading of the clip.

It should be noted that the inwardly extending annular bead provided by the formation of the groove 42 in the holder serves as a limiting stop or abutment for the hair clip by engaging the free end of the leg 36 of the clip when the clip is fully inserted into the holder.

While actual resistance to insertion of the clip is substantially eliminated, the clip is bent sufiiclently, when fully inserted, so that the consequent torsional gripping force of the clip on the holder is sufficient to retain the clip in the holder against inadvertent dropping or pulling out as the handle and tube or rod l2 are turned to curl the strands of hair on the sleeve 10 in its retracted position, during which rotation the holder remains stationary with the hand gripped hair clip. The hair clip holder, therefore, serves in effect as a journal for the outer end of thetube or rod l2 during the rotation of the latter to Wind the strands of hair on the sleeve in.

In the form of the invention shown in Figures 1 to 8, the cylinder 46 with its disk-like member 48 may be formed of sheet metal. In the modification shown in Figures 9 to 11, the member 54 corresponding to the cylinder 46 and disk-like member 48 may be molded from plastic materials. The member 54 comprises angularly spaced, dome-shaped spokes 56 which may be substantially of the same width as the spokes 50 but of considerably greaterthickness and tapering from their outer edges where they are cemented to or frictionally grip the inner surface of the holder to the central dome-shaped section or cam 68, as best illustrated inFigures 10 and 11, the spokes 56 being preferably tapered along their forward within the aperture 34, as previously described, so

as to occupy the position shown in Figures 2 to 5. The ends of a lock of hair are then'positioned be neath the finger I4 by first pressing the finger l6 so as to elevate the clamping portion l4 to the dash line position shown in Figure 3. The end of the lock of hair being preliminarily wound about the sleeve, the finger I6 is released and the spring 26 causes the member I4 to clamp the lock of hair on the sleeve, as shown in solid lines in Figure 3. The handle of the curler is then rotated to curl the lock of hair about the sleeve l0 and the clamping member l4, while the outer end or holder 30 is held against rotation with the hand gripped hair clip 38.

As previously described, the tube or rod l2 and the sleeve I6 maybe freely rotated Without imparting rotation to the holder 36 so that the user need not turn the clip against the gripping force of the holder while the: curl is being wound on the sleeve I6. When the lock of hair has been completely curled upon the sleeve H), the user then grips the curl slightly between the thumb and forefinger of one hand while an outward pull l is exerted on the handle 28 by the other hand,

so that the holder 30 and the hair clip are moved inwardly of the sleeve I0. When the protuberance 22 is engaged by the forward edge of the slot 24 while the curl of hair is still gripped by the thumb and forefinger of one hand, the sleeve in is withdrawn from the curl as the curlis transferred onto the holderand beneath the leg 40 of the clip. Continued pull on the handle, while i the curl is still grasped between the thumb and forefinger, transfers the curl to the clip as the clip is held stationary by the grasped curl and the clip, having already gripped the curl at the outer end of the clip, is thus withdrawn from the holder. farther over the lock of hair.

From the foregoingit will be apparent that my invention contemplates a curler which is extreme:

ly simple in construction and extremely easy of manipulation to form the curl and to place the curl in the hair clip or bobble pin. With this hair curler no preliminary manualspreading of the clip prior to'the application of it to the curling iron is required.
